Flights are expensive. That's a given. But, there are tips and tricks that can help you save. These range from what day you fly and what day you buy.

But now, there's a new way to afford your flights. CheapAir, a flight booking and comparison site like Expedia that pulls flight information from all major airlines, will let you pay for your plane ride with either three, six or 12-monthly payment plans.

But, you guessed it, there's a catch. You'll see anywhere from 10 to 30 percent interest charges, which could cancel out the benefit of the whole thing, depending on who you ask. But on the upside, CheapAir won't charge late fees.

Plus, you'll need to allow CheapAir access to some sensitive data in order to see if you qualify for the financing plan.

A better option could be to just make monthly payments to yourself and save on the interest and the headache and worry over where your personal information is headed.
